Description

一种姜黄素类化合物注射溶液及其静脉注射剂 技术领域
本发明涉及医药技术领域, 是一种姜黄素类化合物注射溶液及其静脉注射剂。 背景技术
姜黄素 (Curcumin ) 类化合物, 是从姜科、 天南星科中的一些植物的根茎中提取 的一种化学成分, 包括姜黄素、 去甲氧基姜黄素、 双去甲氧基姜黄素等。 姜黄素类化 合物不溶于水及乙醚, 溶于甲醇、 乙醇、 丙酮、 乙酸乙酯、 冰醋酸及碱液中。 在光照 和碱性环境中不稳定, 要避光保存。
姜黄素类化合物的主要药理作用有抗氧化、 抗炎、 抗凝、 降脂、 抗动脉粥样 硬化、 抗衰老消除自由基及抑制肿瘤生长等, 并有保肝效果。 但由于姜黄素水溶性 差, 口服时生物利用度低, 且体外稳定性差 (仲明远等, 姜黄素制剂学研究进展 [J].中 成药, 2007,29 ( 2 ): 255-258)。 所以有人将姜黄素制成脂质体、 纳米粒、 β-环糊精包 合物、 微球、 微乳等注射剂, 以提高姜黄素类化合物的生物利用度和药物稳定性。 但 是, 这些注射剂仍然存在以下不足:
1. 姜黄素脂质体,李丽萍等(姜黄素脂质体的制备工艺研究 [J].第四军医大学学报, 2009, 30(24 ) : 3166-3168 ),其用乙醇注入法制姜黄素脂质体的平均包封率仅为 46.69%, 包封率低, 而且需要水浴、 旋蒸等步骤操作时间较长, 不易实现工业化生产;
2.缓释微球, 林媚等 (姜黄素微球的制备及缓释性能研究 [J].福建医科大学学报, 2010, 44 ( 3 ): 178-181 ) , 包封率只能达到 15.6%-62.4% , 可操作性差;
3.姜黄素纳米粒, 刘占军等 (姜黄素纳米粒的制备和释药性能 [J].中药材, 2009.32 (2): 277-279 ) , 姜黄素纳米粒的载药量在 0.3克 /升时包封率最高达 91.6%, 但随着姜 黄素药物浓度的提高, 当载药量为 0.6克 /升时包封率仅为 79.4%, 且包封率随着药物 浓度升高而降低, 成药性差, 在制备过程中要用到水浴, 磁力搅拌, 透析, 操作时间 过长, 操作步骤复杂;
4. β-环糊精包合物, 韩刚等 (姜黄素 β-环糊精包合物的制备工艺研究 [J].中药材, 2004, 27 ( 12 ) :946-948 ) ,在 25°C时,震荡 72小时,测得姜黄素最大浓度为 1.022mg/L, 载药量非常低, 而且制备过程中使用 β-环糊精, β-环糊精具有很强的溶血性, 特别是 有较强肾毒性。
由于上述注射剂存在的种种不足, 所以至今未见姜黄素类化合物注射剂应用于临 床。 发明内容

1、 使用实施例 1所制备的姜黄素静脉注射剂, 将姜黄素注射溶液与乳剂按体积比 1 :50混匀, 检测制剂在不同时间的药物含量、 乳剂微粒粒径以及 pH变化情况。
考察方法为: 取姜黄素注射溶液 2毫升, 将其加入 100毫升的乳剂中混匀成静脉 注射剂; 分别按常规用高效液相色谱、 粒径测定仪、 pH测定仪测定该静脉注射剂在不 同时间点的药物含量、 粒径和 pH值; 以混合后 0时间点药物含量为 100%, 其他时间 点药物含量为注射剂过滤后含量与 0时间含量比较的百分比。 测定药物含量时, 每个 时间点都要测定静脉注射剂过滤前后的药物含量, 即在测定过滤前静脉注射剂的药物 含量后, 将静脉注射剂经 0.22μηι的微孔滤膜过滤, 以去除析出的药物结晶, 再测定滤 液中的药物含量, 每个时间点至少重复测定 2次, 以测得两次静脉注射剂中药物含量 的变化来评价药物是否析出, 若滤后和滤前静脉注射剂中药物含量的比值低于 98%, 则超过系统误差范围视为药物析出, 检测结果平均值见表 1和表 2。

2、 以实施例 16所制备的姜黄素静脉注射剂为例, 将姜黄素注射溶液与乳剂按体 积 1 :50混匀, 检测制剂在不同时间点的药物含量、 乳剂微粒平均粒径以及 pH变化情 况。
考察方法同上, 结果见表 3和表 4.

从表 1、 2、 3、 4看出, 姜黄素静脉注射剂在 18小时内滤液中药物含量几乎没有 变化, 说明没有姜黄素结晶析出; 乳剂微粒粒径也没有明显变化; pH值基本上维持恒 定, 说明姜黄素静脉注射剂在 18小时内稳定性好。 因此, 临床使用前将姜黄素注射溶 液与乳剂混合, 其稳定性、 载药量完全满足临床用药要求。 姜黄素类化合物静脉注射剂对 CC14引起的急性肝损伤的保护实验
1、 实验动物及分组 .· SPF级雄性 SD大鼠 60只, 体重 180〜220克, 在有空调的 动物室饲养, 20〜25°C, 相对湿度 60%, 使用鼠专用饲料, 自由饮水。 将动物称重, 编号, 按体重随机分为 4组, 正常组, 模型组, 给药组 (实施例 1所制得的姜黄素静 脉注射剂)和阳性对照组 (易善复, 批号: 2010051, 赛诺菲安万特公司生产)。 (每组 15只)
2、 动物实验
参照文献李海燕等(狗肝菜多糖保肝作用研究 [J].中药材, 2006, 29 ( 8 ) :833-834 ) 所述, 进行动物实验, 如下- 采用尾静脉注射给药, 每天给药一次, 给药组剂量 10mg/kg (以姜黄素质量计), 阳 性对照组易善复剂量 60mg/kg (以多烯磷脂酰胆碱计), 正常组给予等体积的生理盐水, 于给药第 4天禁食 24小时, 给药组、 阳性对照组及模型组于第 5天末次给药后立即采 用 25%四氯化碳花生油溶液按照 0.5ml/100g皮下注射, 造成急性肝损伤。造模后 18小 时眼内眦取血约 lml, 3500r/min离心 lOmin,采用全自动生化仪测定血清中 ALT、 AST 的含量。
3、 实验结果: 因为 ALT、 AST升高是肝损伤的重要标志, 而 ALT反应肝损伤的 特异程度比 AST高,药物能否有效降低 ALT值是判断药物是否具有抗急性肝损伤作用 的重要标志。 表 5.姜黄素类化合物静脉注射剂对急性肝损伤的保护作用 组别 大鼠数量 ALT AST 正常对照 15 164±19.39 308±84.3 模型组 15 1435.62士 734.73 1756.34±688.29 给药组 15 555士 192.45 976.53±483.51 阳性对照组 15 869.45±262.45 1334.43±628.51 实验结果 (如表 5 ) : 模型组大鼠血清 ALT、 AST含量明显高于正常组 (PO.01 ) 说明造模成功。 与模型组比较, 姜黄素静脉注射剂给药组有明显降低急性肝损伤大鼠 血清中的 ALT和 AST含量, 而且降低量高于阳性对照组, 说明本发明的静脉注射剂 具有明显治疗急性肝损伤的作用。 姜黄素注射剂热压灭菌稳定性考察实验
取姜黄素 2.5克, 加入到 90毫升的聚乙二醇 400中, 70Ό下搅拌溶解, 然后用聚 乙二醇 400定容至 100毫升, 加入 0.10g ( 0.10%wt ) 的生育酚或没食子酸丙酯, 用柠 檬酸调节 pH至 7, 加入 0.35克的针用活性炭, 65°C下吸附 30分钟, 然后用 0.45μπι 的微孔滤膜过滤, 将滤液分装于透明注射剂瓶中, 充氮气保护, 压盖后在压力蒸汽灭 菌器中灭菌 (121 °C、 15min), 取出放冷待用。
分别于灭菌前后的样品中取出 50μ1于 25ml容量瓶中, 甲醇定容后以 HPLC进行 含量测定, 以灭菌前的峰面积为 100%, 比较灭菌前后含量变化,结果如表 6和表 7。
